Yes, fly foods are not the best friends of the metal elements.
There would be two solutions:

1: Purchase incubators that feature stainless-steel elements.

2: Ventilate the incubator. Many incubators feature small holes
    on their wall for installing cables of the electric devices. If
    yours have such holes, leave them open. For even better
    ventilation, you could also install a small fan (such as those
    inside your computers) at the hole. If yours have no hole, ask
    the people in the workshop to drill the wall!

    Such ventilation should, of course, affect the colling/heating
    performance to some extent. You may want to put a thermometer
    to check the temperature stability with ventilation.

Good luck,
